RESUMEN
BACKGROUND: Worldwide, a declining trend is observed in sexually transmitted infections of bacterial origin which is reflected as a rise in the proportion of viral sexually transmitted infections. AIMS: To find out the clinical referral patterns of sexually transmitted infections among patients who attended the sexually transmitted infection clinic attached to Dermatology and Venereology Department of Government Medical College, Kozhikode from 1.1.1998 to 31.12.2017 and to study the linear trends in the pattern of sexually transmitted infections over 20 years. METHODS: After clearance from the institutional ethics committee, a retrospective study was conducted among patients who attended the sexually transmitted infection clinic of Government Medical College, Kozhikode from 1.1.1998 to 31.12.2017 and were diagnosed to have sexually transmitted infections. RESULTS: During the 20 year study period 5227 patients, attended the sexually transmitted infection clinic of our institution. Diagnosis of sexually transmitted infection was made in 2470 (47.3%) cases. Predominant sexually transmitted infections were herpes genitalis (964, 39%), condyloma acuminata (921, 37.9%) and syphilis (418, 17.2%). Viral sexually transmitted infections (1885, 76.3%) outnumbered bacterial sexually transmitted infections (575, 23.3%). A declining trend was noted for both bacterial and viral sexually transmitted infections over the 20 year period, which was more marked for the former. But the latter years of the study documented a rising trend in total sexually transmitted infections including bacterial sexually transmitted infections. LIMITATIONS: The study does not reflect the status of sexually transmitted infections in the general population since it was conducted in a tertiary referral center. CONCLUSION: The disturbing ascending trend recorded in sexually transmitted infections including syphilis during the final years of the 20-year period needs to be watched closely, to plan future strategies.

CONTEXT: Drug reaction with eosinphilia and systemic symptoms (DRESS) and drug-induced hypersensitivity syndrome (DiHS) represent the same spectrum of a drug reaction. AIMS: To compare the clinical profile of patients diagnosed as definite/probable DRESS by the Registry of Severe Cutaneous Adverse Reaction (RegiSCAR) scoring system and as atypical DiHS by Japanese consensus group criteria. SETTINGS AND DESIGN: We did a retrospective study in a tertiary referral center. MATERIALS AND METHODS: We included patients who satisfied the criteria for definite/probable DRESS and/or atypical DiHS and who received inpatient care in our department from January 2011 to December 2018. We compared the clinical and laboratory findings in patients diagnosed by the two criteria. STATISTICAL ANALYSIS: Pearson Chi-square test was used to compare the proportion of patients with severe reactions diagnosed by the RegiSCAR DRESS validation scoring system and the Japanese consensus group criteria. RESULTS: Among the 390 case records reviewed, 138 patients could be classified as definite/probable DRESS and/or atypical DiHS. Japanese criteria did not diagnose atypical DiHS in 88/137 (64.2%) patients with definite/probable DRESS. RegiSCAR scoring system made a diagnosis of definite/probable DRESS in 49/50 (98%) patients with atypical DiHS. A total of 58/138 (42%) patients had a severe reaction. RegiSCAR scoring system diagnosed 57/58 (98.3%) patients with severe reaction as definite/probable DRESS. A total of 32/58 (55.2%) patients with severe reactions were diagnosed as atypical DiHS. The difference was statistically significant (<0.001). CONCLUSION: Japanese criteria for atypical DiHS showed reduced sensitivity to diagnose definite/probable DRESS, and this included more than 40% of patients with severe DRESS.
RESUMEN
CONTEXT: Autoimmune diseases, organ dysfunction and new drug allergies are mentioned as long-term complications after DRESS. There is scarcity of data on this from the country. AIMS: To determine the frequency of autoimmune diseases, organ dysfunction, and new drug allergies after the resolution of DRESS. SETTINGS AND DESIGN: This retrospective cohort study was carried out among patients who received treatment for DRESS in a tertiary referral center. MATERIALS AND METHODS: In this retrospective cohort study, DRESS patients who received inpatient care in the dermatology department of our tertiary referral center from August 2014 to February 2017 were included. We excluded patients aged 12 years or below and those who had not completed minimum two years after the resolution of DRESS as on December 2019. We collected information on new onset autoimmune disease, end organ damage and new drug allergies detected after the resolution of DRESS through a telephonic interview. Those who consented were evaluated in our department. RESULTS: We could contact 40/50 (80%) identified individuals and all of them consented for telephonic interview. 17 patients gave consent for revaluation in our department. There were 22 females and 18 males. 17 had definite and 23 had probable DRESS. The frequency of detection of a new disease and a new drug allergy after DRESS was 10% (4/40) and 7.5% (3/40), respectively. We noted three (7.5%) autoimmune diseases (rheumatoid arthritis 1, alopecia areata 1, chronic autoimmune urticaria 1) and one end organ damage (chronic kidney disease) among the study participants. LIMITATIONS: Small sample size and retrospective study design were the limitations. CONCLUSIONS: Prospective studies with large sample size are needed to delineate the link between DRESS and autoimmunity, end organ damage, and new drug allergies.
RESUMEN
BACKGROUND: Detection of peripheral nerve thickening and nerve function impairment is crucial in the diagnosis and the management of leprosy. AIMS AND OBJECTIVES: (1) To document the cross-sectional area, echotexture and blood flow of peripheral nerves in healthy controls and leprosy cases using high-resolution ultrasound, (2) to compare the sensitivities of clinical examination and high-resolution ultrasound in detecting peripheral nerve thickening in leprosy. METHODS: Peripheral nerves of 30 leprosy patients and 30 age- and sex-matched controls were evaluated clinically and by high-resolution ultrasound. When the cross-sectional area of a peripheral nerve on high-resolution ultrasound in a leprosy patient was more than the calculated upper bound of the 95% confidence interval for mean for that specific nerve in controls, that particular peripheral nerve was considered to be enlarged. RESULTS: Cross-sectional areas more than 7.1 mm2 for the radial nerve, 8.17 mm2 for ulnar, 10.17 mm2 for median, 9.50 mm2 for lateral popliteal and 11.21mm2 for the posterior tibial nerve were considered as nerve thickening on high-resolution ultrasound. High-resolution ultrasound detected 141/300 (47%) nerves enlarged in contrast to the 60 (20%) diagnosed clinically by palpation (P < 0.001). Clinical examination identified thickening in 31/70 (44.3%) nerves in cases with impairment of nerve function and 29/230 (12.6%) in the absence of nerve function impairment. High-resolution ultrasound detected thickening in 50/70 (71.4%) nerves with impairment of function and in 91/230 (39.6%) nerves without any impairment of function. LIMITATION: A single-centre study design was the major study limitation. CONCLUSION: High-resolution ultrasound showed greater sensitivity than clinical examination in detecting peripheral nerve thickening in leprosy cases. High-resolution ultrasound, may therefore improve the sensitivity of the diagnostic criterion of peripheral nerve enlargement in the diagnosis and classification of leprosy.

CONTEXT: Repeated trauma involving extremities (in the setting of peripheral neuropathy) and poor vascularity that impairs wound healing are important causes of disability and deformity in leprosy patients. Nail changes can serve as indicators of trophic changes due to leprosy. AIMS: To describe the onychoscopy findings in leprosy cases and to identify any specific findings in leprosy patients in comparison to controls. SETTINGS AND DESIGN: The first 30 leprosy patients and 30 age and sex-matched controls who attended our tertiary care center from 1 August 2018 were included in this cross-sectional study. MATERIALS AND METHODS: Onychoscopy examination of all fingernails was performed at 50× magnification using dinolite dermoscope AM4113ZT under non-polarizing light to document surface changes and under polarizing light to document pigmentation and vascular changes. STATISTICAL ANALYSIS: The observed nail changes in cases and controls were compared using Pearson's Chi-square test. RESULTS: Statistically significant association with leprosy was found for pitting, onycholysis, melanonychia, transverse lines, nail pallor, and onychauxis. Nail pallor was unique to leprosy patients. LIMITATIONS: Small sample size and not evaluating toenails were the major limitations of the study. CONCLUSIONS: Studies with large sample size are needed to assess the significance of nail pallor as a specific onychoscopy finding in leprosy.
RESUMEN
BACKGROUND: There are conflicting reports on the association between interface dermatitis and hepatic involvement in DRESS. METHODS: A cross-sectional analysis of the clinical and the histopathologic features of DRESS was performed to study the association between the histopathology of the skin rash and hepatic involvement. RESULTS: The clinical and the histopathologic findings were evaluated in 40 cases of DRESS. Thirty patients (75%) had a hepatic involvement. Thirty (75%) biopsy specimens showed a combination of different inflammatory patterns. The interface dermatitis was noted in 24 specimens (60%). Twenty-one patients with the interface dermatitis had a hepatic involvement (P = .04). CONCLUSIONS: The skin rash of DRESS often shows the coexistence of different inflammatory patterns. The interface dermatitis showed a statistically significant association with the hepatic involvement in DRESS.
